Notas do Editor
- QNL also plans to include items from the Museum of Islamic Art in Doha
- Also: Hijri Camara
- Mixed language in title Also n.b. reversed arrows due to reading direction Viewed in Chrome with Gotham Rounded web font
- Spoiler: composed characters safer than decomposed
- Mixed language in title Also n.b. reversed arrows due to reading direction Viewed in Chrome with Gotham Rounded web font
- Same page, viewed in IE9. Diacritics from transliterated title cause crash
- Brand guidelines specify a very stylized font
- Test with native speakers: large blocks of text hard to read
- So switch to standard Arial for web use
- Do not have to compromise design
- Also: different letter forms in Arabic (initial, median, terminal)
- Specifically for QDL, but applicable to online Arabic archives in general
- Viewer on QDL site
